摘要：
A flame retardant polymer composition is described. The composition includes at least one polymer and a hypophosphite salt, wherein the hypophosphite salt is heat stabilized so that when it is heated for 3 hours at 298° C. under a flow of argon flushing at rate 58 mL/min, it generates less than 0.5 mL of phosphine per gram of hypophosphite salt. The flame retardant polymer composition can also include at least one additive that improves the flame retardant properties of the composition.
